A process for preparing detergent particles having a coating layer of water-soluble inorganic material is provided. The detergent particle comprises a particle core of a detergent active material. This particle core is then at least partially covered by a particle coating layer of a water soluble inorganic material. Particularly preferred are non-hydrate inorganic coating materials including double salt combinations of alkali metal carbonates, and sulfates. The particle coating layer may also include detergent adjunct ingredients such as brighteners, chelants, nonionic surfactants, co-builders, etc. The process includes the steps of passing the particle core through a coating mixer such as a low speed mixer of fluid bed mixer and coating the particle core with a coating solution or slurry of the water soluble inorganic material. Upon drying, the resultant detergent particles have improved appearance, flow properties, and improved solubility, and may be packaged and sold as a detergent material or mixed with various other detergent ingredients to provide a fully formulated detergent composition.
Description
Invention field
The present invention relates to detergent particles and preparation method thereof.More particularly, the present invention relates to a kind of preparation method of detergent particles of coating.
Background of invention
Recently in the detergent industry of producing cloth-washing detergent, convenient, attractive in appearance and can be subjected to extensive concern by dissolved liquid laundry detergent product.But the cost problem that has scourability and granulated detergent product.Yet, attractive in appearance, solvability with make things convenient for customer-side to be difficult to overcome with these problems that granular detergent composition was relevant in the past.Generally the appearance of undissolved " concentrating " or low dosage granulated detergent product has more aggravated these problems in washing soln and liquid laundry detergent product thereof.These low dosage washing composition of Present Attitude demand; because they can resources conseravtion; and can sell with small packages, this is very easily before use concerning the human consumer; be distributed in the washing machine it just inconvenient but compare with liquid laundry detergent; when using the liquid machine use washing composition, only need directly from bottle, pour it into washing machine, and during use low dosage washing composition; it " to be scooped out " from box, be distributed in the washing soln then.
Unfortunately, as mentioned above, these low dosages or " concentrating " Betengent product face solubility problem, particularly (that is, are lower than about 30 ℃) in cold washing solution.More particularly, the solvability of this difference can after traditional cycles of washing, form be retained in the washing machine or washing after clothing on outward appearance as " piece " of white solid thing.Under the cold washing condition and/or when the order that joins washing machine be add cloth-washing detergent earlier, inferiorly add clothing, when adding water (being known as " opposite addition sequence " or " ROOA " usually) at last, these " pieces " are general especially.If it is clothing, washing composition that the human consumer joins the order of washing machine, also can form these unwelcome " pieces " when being water then.Equally, this caking phenomenon can cause washing composition in washing machine that is equipped with the dispensing drawer or the incomplete dispensing among other dispensing apparatus such as the granulette.In this case, do not wish that the result who sees has undissolved washing composition residue in dispensing apparatus.
Have been found that: cause " bridging " formation unwelcome " piece " of the reason of above-mentioned solubility problem and intergranular " glue " material that contains tensio-active agent relevant.Tensio-active agent being partly dissolved in wash water solution produces the gelatinoid that makes particle " bridging " form unwelcome " piece ", this being partly dissolved causes the viscous surface promoting agent mutually or the formation of mashed prod, these mutually or mashed prod bonding or " bridging " other particle that contains tensio-active agent form " piece ".This unwelcome dissolution phenomena is commonly referred to the formation of " piece glue ".Except " bridging " effect of viscous surface promoting agent, inorganic salt have the trend of hydration, and this also can cause the particle that links together to pass through hydration " bridging " together.Specifically, form cage structure between hydrated inorganic salt is mutual, its solvability is very poor, finally forms after cycles of washing " piece ".Therefore, thus need a kind of detergent composition that above-mentioned definite problems of dissolution can not occur to improve scourability.
The method of a lot of solutions problems of dissolution relevant with granular detergent composition has been proposed in the prior art.For example, be limited to can be by the consumption and the use-pattern of the caked inorganic salt of hydration " bridging " shape in the cycles of washing for prior art suggestion.Now the someone explore selected inorganic salt concrete ratio so that problems of dissolution minimize.But such terms of settlement has limited the adaptability of prescription and production method, and this adaptability is essential for present business-like scale operation washing composition.Proposed various other mechanism in the prior art, all these comprises and changes prescription that this will reduce the adaptability of filling a prescription.Therefore, need a kind ofly can produce the method that has improved solvability and can too much not hinder the adaptive detergent composition of prescription.
Therefore, need now a kind ofly can produce the method with improved flowability and aesthstic performance and improved deliquescent detergent particles that can be included in the detergent composition.
Summary of the invention
The present invention can satisfy these needs, provides a kind of and can produce the method with improved surface, outward appearance, flowability and improved deliquescent detergent particles.Particle of the present invention has improved surface property, compares with detergent particles of the prior art, and they are more smooth, and more uniform surface and outward appearance are generally speaking arranged.In addition, this particulate outward appearance improves to some extent, and seems brighter whiter than present commercially available detergent particles, and this particle has improved flowability, and its anti-caking and cohesiveness reduce.
The invention provides the method that a kind of preparation includes the particulate detergent composition of water-soluble material coating.This method comprises: the detergent particles with at least a detergent active material is provided, makes these detergent particles by coating mixing tank such as slow-speed mixer or fluidized bed for solid mixing, with the coating solution or the slurries coating particle nuclear of water-soluble coating material.Obtain having improved outward appearance and mobile detergent particles after the drying, can and can be used as the washing composition material with this granule packaging and sell, perhaps mix, make the detergent composition of preparation fully with various other detergent ingredients.
The water-soluble coating material is selected from detergent surfactant such as anion surfactant, hydrotropic agent such as sulfonate, polyoxyethylene glycol and polypropylene glycol, and composition thereof.In preferred embodiments, coating material is that anion surfactant and hydrotropic agent were with about 95: 5 mixtures to about 5: 95 mixed.Particularly preferably be the mixture of (a) linear alkylbenzene sulphonic acid, hydrophobicity secondary alkyl sulfate and/or sodium xylene sulfonate or (b) linear alkylbenzene sulphonic acid, hydrophobicity secondary alkyl sulfate and/or oxidation of alkyl phenylbenzene disulfonic acid disodium (the commercial Dowfax of being called hydrotropic agent, its alkyl chain length are C
1-C
10) mixture, wherein tensio-active agent with hydrotropic than being about 70: 30 to about 95: 5.The amount of water-soluble solution preferably detergent composition weight about 1% to about 30%.Can also comprise the detergent builder composition that joins in the coating such as whitening agent, sequestrant, nonionogenic tenside, second washing assistant etc. in coating material and the particulate coating that obtains thus.
In optional embodiments of the present invention, this method comprises that also detergent particles and flow adjustment (flow control) auxiliary agent with coating mixes so that flow control additive sticks to the step on the particle surface.Preferably mean particle size is less than about 100 microns inorganic powder material, and it is selected from crystalline layered silicate, carbonate, sodium sulfate, pure aluminium silicate, Magnesium Silicate q-agent, Calucium Silicate powder, clay, and composition thereof.
Therefore, the purpose of this invention is to provide a kind of method for preparing detergent composition by coating coated detergent particle with improved outward appearance and flowability with water-soluble material.Another object of the present invention provides and a kind ofly applies preparing washing agent particulate method by solution or the slurries with inorganic materials in mixing tank.Those of ordinary skills can more clearly understand these purposes of the present invention and other purpose and advantage thereof by reading following detailed Description Of The Invention and appending claims.

Particle of the present invention prepares by being coated on the above-mentioned particle with particle coated material in the coating mixing tank.The coating mixing tank can be comprise at a high speed, in middling speed and the slow-speed mixer any one, the Lodige KM that for example describes in detail above
TM(Ploughshare) moderate-speed mixers, Lodige CB
TMSuper mixer or the mixing tank of producing by Fukae, Drais, Schugi or the mixing tank of similar brand.What the present invention preferably used is low speed cylinder mixer and low-shearing power fluidized bed for solid mixing.When the low speed cylinder mixer with in the present invention the time, preferred drying installation and then in the mixing tank back, for example fluidized-bed or rising gas, then in drying installation with the coating particle drying to obtain coating particle of the present invention.But this drying step is chosen wantonly.
In the preferred embodiment of the invention, the coating mixing tank is a fluidized-bed, perhaps is used in combination with above-mentioned any one mixing tank.In a preferred embodiment, the partition ratio of coating between mixing tank and fluidized-bed can be 100: 0-5: 95.Preferred detergent agglomerate particle, spray-dried granules or most preferably be the fluidized bed dryer that its mixture flows into a plurality of inside " section " or " district ".The Duan He district is isolated part in moisture eliminator.These two terms can exchange use.Processing conditions in processing conditions in section and another section can be different also can be similar.Be understandable that: two adjacent moisture eliminators are equal to a moisture eliminator of a plurality of sections.The various logistics of particle and coating material can join in the different sections, and this depends on as the moisture content in granularity and the logistics.Different logistics is joined different Duan Zhongke so that the thermal load on the moisture eliminator minimizes, and can make granularity and the Shape optimization that defines among the application.
Fluidized bed for solid mixing of the present invention generally comprises one first coating region, uses particle coated material of the present invention in first coating region.The coating material that relates in this coating region the aqueous solution or slurries form is sprayed on the fluidized particles.This generally carries out fluidisation with moisture dry or the dry vaporific coating of using of part with adding warm air.Utilization can carry the nozzle that thereby particle can be covered fully to spray the coating compound of particulate or atomizing.The liquid droplet size that comes out from spraying gun is general approximately less than 2 times of grain graininess.Atomizing can be undertaken also can carrying out with traditional pressure nozzle by two traditional fluid tips with atomizing air.In order to carry out such atomizing, the viscosity of solution or slurries generally is to be lower than about 500cp in theory, preferably is lower than about 200cp.Though the position of nozzle in fluidized-bed can be many positions arbitrarily,, preferred positions is to make the vertically spray down of coating material mixture, for example top spray structure.In order to reach best effect, the position of nozzle should particle in fluidized-bed the fluid height place or its on.Fluid height is generally with height of weir or overflow gate high assay.The coating region back of fluidized-bed generally is drying zone and cooling zone.Certainly, those of ordinary skills can recognize to put in order with another and also may obtain coating particle of the present invention.
Condition in fluidized-bed of the present invention or the stirred fluidized bed device generally comprises (i) about 1 to about 20 minutes mean residence time, (ii) not the degree of depth of fluidized-bed be from fluidised bedplate about 100 to about 1200mm or from the fluidized-bed top about 0 to about 600mm, (iii) liquid droplet size is less than 2 times of grain graininess, the drop granularity of spray preferably is not more than about 100 microns, more preferably no more than 50 microns, (iv) about spray height of 150 to about 1600mm, (v) about fluidizing velocity of 0.4 to about 4.0m/s is with (vi) bed temperature is about 12 to about 200 ℃, preferred about 12 to about 150 ℃, even more preferably from about 12-100 ℃.Explanation once more, those of ordinary skills can recognize that the condition in the fluidized-bed can change according to many factors.
Comprise and itself be exactly the detergent composition of preparing fully from the coating particle that comes out of coating mixing tank, in other words in preferred embodiments can with the detergent particles of additional composition such as SYNTHETIC OPTICAL WHITNER, enzyme, spices, uncoated, and various other compositions mix and form the detergent composition of preparation fully.
Utilize method of the present invention can make coating granular detergent composition of the present invention reach the solvability of hope, improve aesthstic performance and improve mobile benefit, and can control or select a certain amount of particulate geometric mean diameter in the composition." improved aesthstic performance " refers to consumer preference the more granulated detergent finished product of single-size outward appearance, and dislikes the granulated detergent finished product or the composition that contain various granularities in the past.In order to reach this purpose, all particulate more preferably at least about 75wt%, even more preferably at least about 90wt%, most preferably have selected median size at least about 95wt% at least about 50wt% in the washing composition finished product.Make most Betengent products have uniform grain sizes by this method, thereby produce the aesthetic appearance that the human consumer wishes.
Preferably about 400 microns to about 1500 microns of particulate geometric mean diameter, more preferably from about 600 microns to about 1200 microns, most preferably from about 600 microns to about 1000 microns.Exceed targeted particle size with less geometric standard deviation or " span " definition size-grade distribution not make too many particle.Therefore, geometric standard deviation preferably about 1 is to about 2, and more preferably from about 1.0 to about 1.7, even more preferably from about 1.0 to about 1.4, and most preferably from about 1.0 to about 1.2.Those of ordinary skills can recognize that the particle of controlling improper granularity by the present invention helps to make the span of the composition that the present invention produces to diminish.
Do not want to be bound by theory, can think: can increase its solvability when the particle of more same particle sizes is arranged in the detergent composition.Specifically, because grain graininess is more evenly the time, " point of contact " actual between the particle in the detergent composition reduces, and is difficult to dissolve relevant " bridging effect " thereby reduced usually with " the piece glue " of granular detergent composition.The detergent composition that had before contained various granularities can form more point of contact between particle.For example, macrobead has many small-particles and contacts with it, and this just makes the particle hole be used to form piece glue.Particulate granularity and homogeneity can be avoided these problems in the granular detergent composition of the present invention.
" part " particle refers in the detergent composition at least some particles and contains detergent surfactant and/or detergent builders to produce the basic structural unit of general detergent composition.Consumption in various tensio-active agents and synergistic agent and each the comfortable composition thereof will illustrate below.In general, detergent composition contains detergent surfactant and about 1wt% extremely about 75% the detergent builders of the 1wt% that has an appointment to about 50%.
The performance of a particularly important of detergent powder is a color.Usually on the Hunter colourimeter, measure color, and represent with three parameters " L " " a " and " b ".Relevant especially with the powder detergent human consumer is the whiteness of using the definite powder of formula L-3b.The whiteness value is lower than about 60% and is commonly considered as very poor.Whiteness be can improve in many ways, pigment or whitening agent such as titanium dioxide for example comprised in the particulate coating.
Another important performance of granulated detergent product of the present invention is single coating of particles of planting.Can measure its shape with many different methods known to a person of ordinary skill in the art.A kind of method is to use the optical microscopy that has Optimus (V5.0) image analysis software.Important calculating parameter is:
" circularity " is defined as: (girth of the particle image of mensuration)
2/ (area of the particle image of mensuration).The circularity of perfect smooth ball (minimum circularity) is 12.57; With
" aspect ratio " is defined as the length/width of particle image.
These performances all are important, can average in a large amount of granular detergent compositions.Incorporating parametric no less important (that is, must control these two parameters simultaneously) by this two parameters of the product of these two parameters definition to obtain having the product of good appearance.Preferably, the circularity of the granular detergent composition of being produced by method of the present invention is less than about 50, preferably less than about 30, be more preferably less than about 23, most preferably less than about 18.It is further preferred that the aspect ratio of granular detergent composition is less than about 2, preferably less than about 1.5, be more preferably less than about 1.3, most preferably less than about 1.2.
In addition, in the particle of composition, preferably have uniform shape and distribute.Specifically, the standard deviation that the number of the circularity of granular detergent composition of the present invention distributes is less than about 20, preferably less than about 10, be more preferably less than about 7, most preferably less than about 4.The standard deviation that the number of aspect ratio distributes is preferably less than about 1, be more preferably less than about 0.5, even be more preferably less than about 0.3, most preferably less than about 0.2.
